[scrimegour]

hey everyone

im about to fit extractors and a 2" exhaust on my 98 sierra and
was wondering if anyone has extractors, 2" exhaust or both on there zook
and what sort of difference it made and is it worth doing at all?
thanks guys

[zoozookey]

hey fellas

i'm about to do the same thing to my coily, i've got 196000 k's on the clock and she's gettin a bit tired, it's so painfull dropping back to third on the highway just to hold 100 when you got a head wind LOL :D

can anyone let us know how they went with there extractors and exhaust as in how much and what size exhaust and any other info.

there are extractors on ebay for $180 delivered, sounds good to me.
anyone used them? CHEERS!

hey mate yea ive ordered a 2" system with cat no extractors was gonna be to expensive at the moment by the way zoozoo are u the new high bidder on those extractors ??

[GRPABT1]

I bought the ebay Genie headers and got a GTi flange welded to them to suit my twin cam motor and a 2inch press bent system with high flow cat and straight through muffler. It cost me $500 not including the extractors which I got stung for cause I wanted them right then and someone was trying to out bid me.

That said I am about to get the muffler changed to a turbo style or something because it's too bloody loud.

[scrimegour]

does it really get that loud ?? hmm might be a problem will have to see. the system (hi-flow cat and muffler 2" pipe) on my zook is costing me $260 without the headers tho now i have been out bid on the headers ill have to find some cheapys somewhere else.... anyone know where i can get some around or near dural/castle hill??

also does a hi flow catalytic converter make any difference or can i just stick with the 2",muffler......and headers if i find them.. ?

thanx guys

[zoozookey]

hey that sounds like a pretty good price with a high flow cat.

and it wasn't me who bid on them. i've been watching those extractors for a few weeks now cause they're always relisted and the last couple of times before this one there was only one bid so $180.

fust keep an eye on them they're always there :thumb:

[GRPABT1]

The cat is the biggest restriction so yes it makes a difference and my sook doesn't have a back window hence it sounds louder in the cabin but still with the really short wheel base of a sierra there isn't much length in the exhaust so the mufflers are working harder to muffle the sound then if you had more pipe length if you know what I mean.

[zoozookey]

hey GRPABT1

i've heard from a few different people with soft top zooks that if you run the exhaust tip out the side behind the rear wheel, rather than straight out pointing rearmost it makes an improved difference on noise as well as fumes when the soft tops on. not sure how effective but been told it works.

might be a cheaper option to try before getting a different muffler, jst a thought.

[scrimegour]

hey ive got another question with the white hose that connects to the ducting for the airbox and to the headers what do you do with that pipe with new extractors seeing there is now no where to put it.... if u took the whole thing off it would lower the air in take wouldnt it ? also will it make the car not want to start in the cold ????

thanx

[croatian4x4]

It is debatable has to how much difference a hiflow cat makes to a standard zookie cat.......... as they say, if it aint broke, dont fix it!

i have a 2" system using wild cat extractors an a highflow muffler and standard cat (as mine was fine, no cracks), cost me $440 installed

[GRPABT1]

Have you ever looked at a standard cat next to a high flow? I have done before and after dyno tests on my V8 with normal then high flow cats and picke up a few KW without touching the tune. I'll say it again, they are the biggest restriction point in an exhasut system. If you want to go cheap (why when 2 inch high flow cost bugger all) get 2 standard cats and split the pipe and run twins.

[croatian4x4]

If you gained only a few extra KW out of a v8 using a high flow cat opposed to a standard, how much you reckon you would gain out of a tiny 1.3ltr. Get real mate, the power difference would be bugger all, why waste anymore money on the car just to gain a measly 1 or 2 kw, when that money could go towards something a little more effiecient....like fuel....

[GRPABT1]

Gains of a few KW on a <100hp 1.3L are far more significant than on a 300kw V8, and like I said that was untuned. With a carby 1.3L you go tune it easily and gain more. If you are doing the whole exhaust then you will need a new cat anyway cause they only last 50000km (less if you motor is running rich or they get really hot like in modern cars with them attatched to the header), and in 2 inch the price difference is marginal. I paid more for one of my high flow 2.5inch cats for my commodore than the whole exhaust for my suzuki which includes a high flow cat and muffler.

[croatian4x4]

my cat has done 125,000km, just had new 2" system put on with extractors minus the cat, as the cat was in absolute perfect working order, no idea where you get the bs "only lasts 50,000km" crap. 90% or ppl i know have way more then that many km on the original cats, hell my old man has got over 300,000 on his cat in his cruiser and there is no problem with ti watsoever.

Until you can provide me with a dyno of a standard 1.3, then one of the exact same engine with a full system minus the cat, and then one of the same engine with a full system with the cat u can jam all the jibberish you are speaking in the bin. It will make fark all difference.

Other then that, here i will give you a big kiss (K).

[zoozookey]

ummmm ok

well after all that Would both of you agree that the power or performance gain from a 2 inch system with extractors, with or without a high flow was considrably improved???

if so then GREAT that's all that's needed to convince me to do it.
wether or not i use a high flow depends on $$$$$.

as for extractors i would buy the ones off of ebay however there a bit rich at the moment.

Crotian4x4 where did you get wildcat extractors from?

also i just had a quick search on ebay and high flows for 2+half as well as 3 inch were $179 - $229. is that good??

no intention to cause dissagreement or anger!!
just want some different opinions and experiences!!
CHEERS:thumb:

[mick85]

genie/wildcat (both pretty even cost and performance wise) should do a a set for a pretty low price, everywhere sells them.

[scrimegour]

so like zoozoo said is the a power increase or isnt it really worth the $$$

also to get some extractors talk to "suzisport" theres one in seven hills they have good price.

[GRPABT1]

For those sizes that is bloody cheap, but that would raise questions of quality.

[GRPABT1]

Have you had these cats withs 100000km+ tested by epa for emissions? I think not, so then how the hell can you tell if they are "in perfect working order". I guess I just like to spend a little to do it right the first time.

[croatian4x4]

ummmm ok

Improved - Yeah for sure, i reckon i can notice a slight difference

Considerably - Nope. I dont notice anything massively different, even in my mates zook that HAS got new high flow cat as well as extractors and 2" system, it sounds pretty kool, but performance wise no where near the bang for buck. Might gain a couple extra kw at most.

Save the dosh, spent it on something else more productive then a "better" sound......like a bigger motor :D

Me? well i like the sound and money was just lying around :D :waycool:

[zoozookey]

Righto So!!!

at this stage not having alot of money to throw around, i reckon i would be better off saving for some transfer gears to fit some 31s not too far down the line rather than a couple of hundred on a exhaust that sounds the goods but isn't really needed.

THOUGHTS?????

at the moment i'm runnin 235/75 15 couragia federals m/ts
2'' body and a few suspension tweaks, apart from that she's standard everything else.
the tyres have sucked the power noticeably but i can still manage in 1st low. however on the highway i'd hate to have to drive up to hotham once a week for work cause it's a bit of a turtle lol!

[croatian4x4]

good decision mate.
You will get a lot more rewards for some transfer gears then you would for a zorst. You will even get 5th gear back on the highway running 31s! :D

[zoozookey]

yeh mate sounds like i'll be headed that way.
stage 3 gears seem to be the goin thing with 31's yeh?

i overhauled my starter motor and alternator during the week and now it's so quiet. before i used to listen to the grind of the bearings to know my rpm lol!
a few water crossings and some nice red dirt soup and it'll be back i spose.:truck:

[zoozookey]

Hey scrimegour.

didn't mean to highjack your thread mate :o

let us know how you go with your exhaust and any other mods!!

CHEERS:thumb:

[scrimegour]

hey mate naa you guys are right u have been asking questions ive wanted to know the answers to anywayz so its ok

and yea got the exhaust on today with the headers all up $400 and guys it does make a difference very noticeable one also has a nice deep tone to it now.

well yea anywayz next up is a bullbar and side rails maybe a lift.

cyaz for now

[GRPABT1]

Good stuff mate, glad you're happy. Must have been a bit restrictive to notice a big difference, just out of interest (don't want to start abother shit fight) did you go the high flow cat or not?

[croatian4x4]

lol was waiting for it.......:p

ahah its ok GRPABT1 I still bloody love ya;) hehe

[rustyzook]

hey ive got another question with the white hose that connects to the ducting for the airbox and to the headers what do you do with that pipe with new extractors seeing there is now no where to put it.... if u took the whole thing off it would lower the air in take wouldnt it ? also will it make the car not want to start in the cold ????

thanx

i took the hose off mine after a water crossing :mad: the thing ducts water straight into the airbox and stops the snorkle working! lesson learnt after pulling the plugs out and a few hours drying it!!! the next deeper river crossing the airbox lid didnt really work so check ya seal on that to LOL!

some people my not aggree with me! but it fixed my water crossing problem!

[GRPABT1]

I looked at a carby swift motor with a similar cold start hose thing the other day and it was all corroded and holey, so not doing alot anyway. I'd piss it off and seal it up, just make sure you warm her up in the morning.

[zoozookey]

hey all

i pulled the rear section of my exhaust off today (just out of boredom), unbolted the flange after the cat and started it up. i was expecting alot of noise but honestly i was dissapointed, either my cat is absolutely farked or i was expecting to much from a 1.3L AGAIN. lol:D

well i HAD to take it for a drive after that and i was still dissapointed.
it was quiet and burbled a bit when you back off but under excelleration it was sad haha.
i know it's no big performance exhaust but i was expecting a little more.

hey also has anyone removed there air box and replaced it with anything else. i was thinking of pulling it all out and running a air box over to the passenger side with a box out of something that has a flat panel filter or some other cheaper option and running a snorkel out the passenger guard ready for a 1.6 transplant...... THOUGHTS? CHEERS FELLAS!

[GRPABT1]

I run a MK1 swift GTi box and panel filter modified for some more flow in mine similar to what you are suggesting but on the dirvers side. You would be best off getting a pod filter and making a sealed box with snorkel. Although it's all money better spent on a new engine :P

hey everyone

im about to fit extractors and a 2" exhaust on my 98 sierra and
was wondering if anyone has extractors, 2" exhaust or both on there zook
and what sort of difference it made and is it worth doing at all?
thanks guys

I fitted a set of extractors to my '98 coily a little while back (bought off GRP Auto in Sydney a few years ago, only got round to fitting them just recently) and fitted a Lukey Turbo muffler in place of the original on a custom 2 inch system that I made myself (welded, not mandrel bent).
At the same time, I used a holesaw to cut two holes in the air filter box to get some more air in and bought PVC pipe plugs to plug them up for water crossings. Difference ? Try 120 kmh top speed with standard exhaust (on 215/75 tyres with a 2 inch lift) and 135 now... (all under controlled circumstances of course ;) ). Now tell me it doesn't make a difference.
Oh, and I get better fuel economy as well...

Cheers,

[GRPABT1]

How loud is the turbo muffler? Cause I ws going to swap my straight through with a turbo cause it's too loud.

[scrimegour]

hey guys took it to stockton beach on Fri and sat on the free way i got to 140 easy tho zook go bit light in the steering at tho speeds but yea and it was flyin around the dunes in 2wd by the way yea i got the whole thing with the cat.

cyaz

[GRPABT1]

Good stuff, That's similar speeds mine gets with the GTi motor and bigger tyres.

[ZookNC]

How loud is the turbo muffler? Cause I ws going to swap my straight through with a turbo cause it's too loud.

It is a bit loud, particularly on long trips, although I get a lot less attentions from the boys in blue than when I ran a single hot dog type muffler (now THAT was LOUD). When this one is dead, I will get one of the more expensive straight through Ultra Flo models from Lukey with all stainless baffles and stainless steel wool and fiberglass packing. They're supposed to be a lot quieter than what I have now and even better performance.

[GRPABT1]

I would imagine a straight through would be louder than a turbo muffler. I've got a straight through in mine now and it's rediculous. It's awsome cause it sounds like a race car but you can't here the passenger yelling at you.

[ZookNC]

Oh yeah, it's much quieter. You still get that race car type sound though not so loud, more burbley. What I like about it is you still get the crackle on the overrun going down hills... really sounds the goods ! :thumb:
This said, a system with a bit of back pressure (as compared to a straight through like yours) will increase low and mid range torque as well.

Cheers,

As above I too have extractors, but with 2inch exhaust,running 235/75/15,
no mods apart from rear spring having a negative camber (heavy/load).
Yes the power increase is very noticable and economy is good.As for noise ,its a hard top 88' so only when you gun it does she really speak out.
Going up a hill (tarseal) use to have to drop to 4th or even 3rd to keep speed up.Now can do it with ease in 5th .Speed increase yes, but I don't like going over 100k's.The power and pick up are there though.
ie: drop(gear) and plant(foot)Price $800 including labour that's extractors and exhaust.Bout 4 yrs ago.Do it if you still want to have a "little monster",the economy /power inrease are worth it.
Just answering the original question....cheers....
